Provided is an information recording apparatus which, in a state where the content of moving picture image information, etc. can be prevented from being inadvertently recognized by the user due to inadvertent presentation to the user of a relevant representative picture image, enables recording the respective information into a recording medium. A reproduction list PL that is to be reproduced is not only recorded into an optical discbut is there also recorded in it a reproduction list display prohibition flag PHF indicating at least whether limiting the display of a representative picture image that represents the content of the reproduction list PL.

Apparatus for and method of recording information, apparatus for and method of reproducing information, recording medium, and information recording medium

Provided herein are: a data acquiring unit which acquires a plurality of angle video data equal or less than the angle video data and relative display position information from a recording unit which records the plurality of angle video data corresponding to the plurality of angle videos taken at a plurality of taking angles different from one another in which a taken object is taken and records the relative display position information indicating a relative display position of each angle video in consideration of each taking angle; a video signal output unit which outputs a plurality of angle video signals corresponding to the plurality of angle videos to display units based on the plurality of angle video data; and an arrangement determining unit which determines a display position arrangement of the plurality of angle videos based on the relative display position information.

Video reproducing apparatus, video display system and record medium

An information record medium comprises video information for indicating a main-video, sub-video information for indicating a sub-video which can be displayed at least partially over the main-video, and sub-video control information including (i) a plurality of types of control information elements for display control of the sub-video information in various methods set in advance and (ii) type indicating information to indicate presence or absence, or effectiveness or ineffectiveness of the control information elements by each of the types.

Information recording medium, information recording device and method, information reproduction device and method, information recording/reproduction device and method, recording or reproduction control computer program, and data structure containing control signal

On an information recode medium, a whole stream containing a plurality of partial streams each consisting of content information including still picture information is multiplexed and recorded on packet basis. The information record medium includes a file for storing object data consisting of a plurality of packets each containing a fragment of content information and a file for storing information defining the reproduction sequence of the object data. Furthermore, the information record medium includes an object information file for storing classification information indicating whether each object data corresponds to a first encoding method or a second encoding method.

Information record medium, information record device and method, information reproduction device and method, information record/reproduction device and method, recording or reproduction control,computer program and data structure including a control signal

To limit the time capable of reproducing a plurality of contents as a whole recorded on a recording medium. Provided herein are a recording medium on which a plurality of contents and reproduction-enabled time which is a period of time for allowing a user to freely reproduce the plurality of contents as a whole are recorded, a reproduction device having an acquisition unit which acquires the reproduction-enabled time and a reproduction inhibit unit which inhibits the reproduction of each of the contents when the accumulated reproduction time of the plurality of contents as a whole exceeds the acquired reproduction-enabled time during the reproduction of each of the contents.

Reproduction system

An information recording medium on which a plurality of stream groups are multiplexed and recorded by a unit of packet, which is a physically accessible unit, each of the stream groups including one video stream, the information recording medium provided with: an object data file for storing object data which comprises a plurality of packets; and an object information file for storing correspondence definition information for controlling the reproduction of the object data. The object data is divided by a divisional unit in at least one portion of a reproduction section, which is provided with the plurality of packets and corresponds to one of the plurality of stream groups. The object information file stores unit address information indicating an address of each of divisional units, as the reproduction control information.

Information recording medium, information recording apparatus and method, information reproducing apparatus and method, and computer program for record or reproduction control

An information recording medium () is provided with: a first area in which first data is recorded, first data region information being assigned to the first data; a second area in which second data is recorded, second data region information being assigned to the second data; and a control area in which control data including setting command data () is recorded, the setting command data setting the first data region information as reference region information, which is referred to by an information reproducing apparatus, if the first data is reproduced.

Information recording medium, information recording device and method, and computer program

A series of content information; menu information, which is to be displayed with the content information during reproduction of the content information; and play list information for defining reproduction sequence of the content information by a unit of item, which constitutes the content information and which is accessible upon reproducing, are recorded on the information record medium. The play list information includes: item information for specifying each item which constitutes the content information; and slave item information for specifying the menu information corresponding to the each item as a slave item.

Information recording medium, information recording device and method, information reproduction device and method, information recording/reproduction device and method, computer program for controlling recording or reproduction, and data structure including control signal

An information record medium contains video information indicating a main-video, sub-video information indicating a sub-video which can be displayed at least partially over the main-video, and sub-video control information including sub-frame range information specifying at least a part of the region in the sub-video as a sub-frame and sub-frame control information for controlling display of a sub-frame displayed over the main-video. The sub-frame control information includes dynamic control information includes dynamic control information for dynamically displaying the sub-frame.

An information recording apparatus (SSI) is provided with: a signal process device () for applying a predetermined signal process to a plurality of partial record information blocks constructing whole record information (R) to thereby generate processed partial record information blocks (Sr) each composed of a plurality of predetermined information units (IU), and for generating and outputting recording position information (Sac), which is to be recorded by each of predetermined reproduction units (VOBU) composing the information units, for respective one of the reproduction units. The recording position information indicates recording positions of the reproduction units corresponding to reproduction times of the partial record information blocks within a predetermined range before and after the respective one of the reproduction units on an axis of reproduction time of each of the partial record information blocks. The information recording apparatus is also provided with; a multiplex device () for multiplexing the processed partial record information blocks and the recording position information by each of the reproduction units to thereby output multiplexed partial record information (Sap); and a record device () for recording the multiplexed partial record information onto the information record medium.
